Title: Two-stroke cycle internal combustion engine
IPC: F02B75/02
Filed: 1930-04-28
Abstract: 347,006. Two-stroke engines. STREIT, M., 42, Hohenzollernstrasse, Breslau, Silesia, Germany. April 28, 1930, No. 12989. [Class 7 (ii).] In a two-stroke engine having two pistons working one within the other so as to form a pump space between the two piston heads, a further pump space is provided between enlarged diameters of the pistons. The upper piston 12 is formed integrally with a sleeve 12<11> which is of larger diameter than the piston. Inside the skirt of the upper piston and its sleeve extension works a second piston 6 of two diameters, and to the larger end 611 is attached a sleeve valve 3 which controls the exhaust ports 4<1>. The inner piston 6 and the sleeve 3 are connected to the crank shaft 9 by a connecting rod 7. The outer piston 12 carries surfaces 13 which bear against cams 14. The sleeve valve passes through slots 21 in the piston 12. During the power stroke, the heads of the two pistons are in direct contact and both travel downwards together. As the sleeve 12<11> uncovers the inlet ports 2<1>, combustible mixture flows into the space 20 between the parts 6 and 12<11> of the pistons. The cam 14 then raises the piston 12, while the piston 6 and the sleeve valve 3 still descend. The exhaust takes place through ports 4<1>. Mixture is drawn in to fill the pump space 19. The sleeve valve 3 and the piston 6 then rise, and the piston 12 remains stationary under the action of the cam 14. The sleeve 12<11> closes the inlet ports 2<1>, and the mixture in the space 20 is forced through slots 11 in the piston 12 to the pump space 19 and through a valve 17 into the combustion chamber 18 above both pistons, where it is compressed and ignited. In a modification, air is drawn in through the ports 2<1> and the igniting device is replaced by a fuel pump delivering heavy oil to the cylinder head.

Abstract: 745,448. Arc-welding electrode holders. QUASI-ARC CO., Ltd. June 1, 1954 [May 12, 1953], No. 13247/53. Class 39(3). An arc -welding electrode 14 is held in openings 13 in a hollow cylindrical metal body 10 by a plunger 15 sliding in the body 10 and pressed by a spring 19, the plunger being moved to grip or release the electrode by a pin 26 working in a helical slot 27. The pin 26 is mounted on a piston 24 sliding in the member 10, in the wall of which the slot 27 is formed ; and the pin projects into a longitudinal groove 28 in the wall of a collar 29 rotatable on the member 10. An insulated handle 30 or guard ring 32 is attached by a screw to the collar 29 so that on rotation of the latter, the piston is moved in one direction to compress the spring 19 against the end of the plunger 15 to clamp the electrode ; and on rotation of the collar in the other direction, the piston moves back to free the spring and to bear on a head 35 of a rod 34 sliding in the piston and attached to the plunger 15, which is thereby positively retracted from the electrode. A supply cable 36 is sweated into a ferrule 37 screwed into the end of a plunger 10. In order to prevent release of the electrode during welding a recess is formed in the forward end of the helical slot 27 to retain the pin 26 therein by pressure of the spring 19. The collar 29 may be of square or hexagonal cross section in order to leave passages between the collar and the tubular handle into which air may enter through openings in the guard ring to cool the holder. In Fig. 6 (not shown) the collar 29 is attached to the guard ring 32 and the handle is attached by a peg to the ferrule 37, which screws over the end of the member 10. The front part of the member 10 may be attached by a screw thread to the main part thereof, so that on removal of the front part the piston 24, spring 19 and plunger 15 may be inserted through the front ; and in this modification the central bore of the part 10 does not extend wholly to the rear thereof, which is solid and is recessed to receive the cable. In another modification (Fig. 8) the helical slot 27 is formed in the collar 29 and a co-operating longitudinal slot 44 is formed in the body 10 ; and a clip 45 holds in place the collar 29, which is preferably not of the split type.
